Command to see the last lines of a file directly in the terminal.
By default, it shows the last 10 lines of a file.
To get a different number of lines you can use the
-n number option
tail -n 2 filename # Shows 2 lines tail -n 100 filename # Shows 100 lines
Tip: to see all lines of a file is best to use the
-f – Used to “follow the file”. This shows the last lines and keeps waiting for new lines, showing them when the file gets updated.
This flag is ideal to check real-time logs.
tail -f file
Use the manual for all the available flags.
